“…While this may help guide them, it does not allow guiding the blind safely and autonomously in closed spaces. However, there are solutions for this [12], although they require bulky hardware, which prevents the dimensions of the device from resembling that of the canes normally used as an aiding tool by the blind population, thus limiting its natural use.…”

Context: Blindness is a physical-sensory disability that limits the ability of affected people to carry out daily-life activities and deteriorates their quality of life. It is estimated that there are 296.000 blind people throughout the Colombian territory. Method: This article presents the development of an electronic baton that works with a system of guiding lines and information points, together with an application for mobile devices. This research is based on the quantitative method, seeking to investigate the characteristics of the device in terms of its use. A descriptive investigation is performed which can be classified as ex post facto. Results: As a result, a device is developed which can guide a blind person to their destination in closed areas, although the time used for movement is greater compared to a journey with human assistance. Conclusions: There are solutions aimed at guiding a blind person in closed spaces that achieve this goal, although they require bulky hardware, which prevents the dimensions of the device from resembling those of the walking sticks normally used as a tool by the blind population. This limits the natural use of this kind of devices.

“…GPS is a satellite-based system that provides the location of the GPS device by indicating the longitude and the latitude of the location. Some researchers have proved that the GPS cannot function properly in an indoor space and they have presented the solution of GPS by using the IrDA technology, which works as a detector to guide visually impaired people in an indoor environment [24]. On the other hand, Lisa et al combined the GPS that have developed in Drishti system and the ultrasonic sensors to be used for outdoor and indoor navigation [25].…”

In general, a visually impaired person relies on guide canes in order to walk outside besides depending only on a tactile pavement as a warning and directional tool in order to avoid any obstructions or hazardous situations. However, still a lot of training is needed in order to recognize the tactile pattern, and it is quite difficult for persons who have recently become visually impaired. This chapter describes the development and evaluation of vision-based tactile paving detection method for visually impaired persons. Some experiments will be conducted on how it works to detect the tactile pavement and identify the shape of tactile pattern. In this experiment, a vision-based method is proposed by using MATLAB including the Arduino platform and speaker as guidance tools. The output of this system based on the result found from tactile detection in MATLAB then produces auditory output and notifies the visually impaired about the type of tactile detected. Consequently, the development of tactile pavement detection system can be used by visually impaired persons for easy detection and navigation purposes.

“…The design challenges for the blind navigation device are real-time guidance, portability, power limitations, appropriate interface, and continuous availability, no dependence on in-frastructure, low cost solution and minimal training [8]. There are several designs to help visually impaired people to achieve self-independence traveling at indoor environment.…”

Abstract-Conventionally, visually impaired people using white cane or guide dog for traveling to desired destination. However, they could not identify their surround easily. Hence, this paper describes the development of navigation system which is applied to guide the visually impaired people at an indoor environment. To provide an efficient and user-friendly navigation tools, a navigation device is developed by using passive radio frequency identification (RFID) transponders which are mounted on the floor such as on tactile paving to build such as RFID networks. The developed navigation system is equipped with a digital compass to facilitate the visually impaired people to walk properly at right direction especially when turning process. The idea of positioning and localization with the digital compass and direction guiding through voice commands is implemented in this system. Some experiments also done which is focused on the calibration of the digital compass and relocates the visually impaired people back to the right route if they are out of the direction. Besides, a comparison between two subjects which are human and a mobile robot is made to check the validity of the developed navigation system. As the result, the traveling speed of human and mobile robot is obtained from the experiment. This project is beneficial to visually impaired people because the navigation device designed with voice commands will help them to have a better experience, safer and comfortable travel.
